It may be often desirable according to the exigencies of the moment, notto use the locking or interfering mec ianisin. In such an eventadvantage can be taken of the fact that the books 6 of the links 7 areope:- atively disconncctible from the jaws t and 5 b slipping outthrough the opening at one side. The links 7 can be manipulated in anysuitable manner for this purpose, astor enaniple, by a shifter or red 17which is shown as operatively connected thereto by being provided withslots 18 through which the links extend. The rod or shifter 17 may beoperated in any manner suitable to the requirements, either manually orautomatically.

l hile I have shown one embodiment 01 my invention, I do not wish to belimited bv the specific details thereof, but desire to be protected invarious changes, alterations and modifications which may come within thescope of the appended claims.

Having thus described my invention, I claim:

1. The combination with a set of keys, of a set of blades connectedthereto, said blades movable by their keys to a position common to allthe blades, so that when one blade occupies such common position theother blades and their kevs are prevented from operating.

2. The combination with a set oi keys. of a set of blades connectedthereto. said blades movable bv their kevs to a position common to allthe blades, so that when one blade occupies such common position theother blades and their keys are prevented from operating, and supportsfor said blades in proximity to said common position.

3. The combination with a set ot kevs. ot a set of supported bladesdiverging from a common center and connected to said kevs to be movedtherebv to said common center. so that any blade. upon moving to saidcon. mon center, mav prevent the operation of any of the remainingblades and k i. The combination with a set of ke vs, ot a supportingdevice having a centrzl opening and slots radiatin r from said opening,and blades supported in said slots and connected to said keys to be movd thereby into said opening. to enable each bla dc to prevent theoperation of the rou'iaining' blades and their kevs.

The combination with a set of keys. of a set of divereing leversconnected thereto. and a set of diverging blades provided upon saidlevers and movable bv said kevs to a common position to enable eachblade to intercept the remaining blades.

6. The combination'with a set of hea s, of a set of diverging leversconnected thereto,

keys, of locking niechan intense and a set of diverging blades providedupon said levers and movable by said ke s to a common position to enableeach blade to interceptthe remaining blade and a support having radialslots in which said blades are guided.

7. The combination with a set of kevs. of a set of diverging leversconnected thereto. and a set of diverging blades provided upon saidlevers and nmvable by said kevs to a W common position to enable eachblade to intercept the remaining blades. and a support having radialslots in which blades are guided. the blades being; in the form o l Inicnts curved about the pivots of their resoective levers.

8. The combination with a set oil kevs, ol' oi? diverging leversconnected thereto. and a of flll'tl" 'ng blades provid d upon by saidkeys u a said levers and movable common position to ible each blade tointercept the remaining blades. the connection between said love s andsaid kevs being such that the one can be detached from the other, sothat said lKG'YS may operate freely independent of said levers.

9. The combination with a set ot kevs. of a set of movable obstructingmembers operativelv connected to said have. one of each of the lattercorresponding to one of each of the former, said members mm'infindividually to a position in the path of movement of the rest of saidmembers, so as to prevent the simultaneous complete actuation of two ormore members and thereby prevent the simultaneous actuation ot tivo ormore kevs 10. The con'ibination with a set oi he of a set of movableobstructing members operativelv connected to said keys. one of each ofthe latter cm'respondinp' to one ot each of the former, said membersmoving individually to a position in the path of movementot the rest ofsaid members. so as to prevent the simubaneous con'i iletc actuation oftwo or more mei'nbcrs and there no by prevent the siu'niltaneousactuation of two or more keys.

14:. The combination with a plurality of I keys, of a member cooperatingwith eachi of said keys to lock certain of the others of said keys, byinterfering with the action of said members corresponding to said keeach of said members being opel'atively d connectible from said keys soas to permit such keys as are disconnected to move independently of thelocking or interfering action of said members.

15. The combination with a plurality of keys, ot'a member cooperatingwith each of said keys. to lock certain of the others of said keys, byinterfering with the action; of said members corresponding to said keys;each of said members being operatively disconnectible from said keys soas to permit such keys as are disconnected to move independently of thelocking or interfering action of said members, and a shifter forcontrolling the operative connection of a plurality of said members withsaid keys simultaneously.

16. The combination with a key, of a pair of jaws connected to said keyand spaced apart from each other, a link adapted to extend in a. spacebetween said jaws so as to be operatively connected to said key, and aninterfering or locking mechanism connected to said link.

1.7. The combination with a key, of a' pair of jaws connected to saidkey and spaced apart from each other, a link adapted to extend in aspace between said jaws so as I to be operatively connected to said key,and i an interfering or locking mechanism coni nected to said link, thespace between said 1 jaws being open at one side so that said link 5 canmove into and out of the space between i said jaws so as to operativclyconnect and disconnect said link with said key. one of said jawsprojecting bc \'ond the other of;

18. The combination with a key, of a link detachably connected to saidkey, an intertering or locking member connected to said l link. and abar having a slot therein through which said link extends for shiftingsaidlink to connect and disconnect the same with said key.

19. The combination with a plurality of keys each having a pair of jawsseparated to form a space open at the same side, of a plurality of linkshaving h0ok-shaped portions mo able into and out of the space betweensaid jaws through said open sides, locking or interfering mechanismconnected to said links so as to be controlled by, and

likewise control the action of said keys, and a shifter for mampulatingsaid llnks, so as to operatively connect and disconnect the same withsaid keys by moving them into and out of the space between said jaws.

20. The combination with a plurality of keys each having a pair of jawsseparated to form a space open at the same side, of a plurality of linkshaving hook-shaped portions movable into and out of the space betweensaid jaws through said open sides, locking or interfering mechanismconnected to said links so as to be controlled by, and likewise controlthe action of said keys, and a shifter for manipulating said links, soas to operativcly connect and disconnect the same with said keys bymoving them into and out of the space between said jaws, one of saidjaws having means for preventing the disalinement of the hook-shapedportions of said links with said spaces between said jaws.
